UNITED. STATES PATENT OFFICE.

GEORGE E. BAILEY, OF MANSFIELD, MASSACHUSETTS, ASSIGNOR TO GEORGE E. BAILEY dz SONS, OF SAME PLACE.

BAKERS OVEN.

SPECIFICATION forming part of Letters Patent No. 411,180, dated September 1'7, 1889. Application filed February 25, 1889. Serial No. 301,114. (No model.)

To all whom it may concern.-

Be itknown that I, GEORGE E. BAILEY, a citizen of the United States of America, and a resident of Mansfield, in the county of Bristol and State of Massachusetts, have invented certain new and useful Improvements in Bakers Ovens, of which the following is a full, clear, and exact description.

Under this invention the furnace or combustion-chamber is located under the oven chamber and separated therefrom by an inclosed air-chamber located directly under the floor of the oven, and fines are provided leading from the furnace and opening into the oven-chamber at its top portion and from the oven-chamber to the chimney or escape-flue, and all otherwise substantially as herein after described.

In the drawings forming part of this specification, Figure 1 is a section on the horizontal plane of the oven floor, the floor being removed, as also the roof of the furnace. Fig. 2 is a transverse vertical section,line 2 2,Fig. 1. Fig. 3 is a plan view of the oven-chamber overturned and its floor removed. Figs. 4 and 5 are vertical sections from front to rear of oven,lines 4 4- and 5 5 respectively, Fig. 1.

In the drawings, A represents an outer casing, to be built of brick or other masonry or suitable material.

B is the oven-cl1amber,inclosed by the masonry A and having a communicating door 0.

D is the floor of the oven-chamber, oonstructed, by preference, of tiles, as Well known, supported at suitable points on brick columns C resting on the floor of an inclosed airchamber or space E, located directly below the oven-floor and constructed of masonry in any suitable manner.

F is the furnace inclosed in and located at one side of the masonry A and having a firegrate F and feed and ash doors F F, all as well known. This furnace F is below and separated from the inclosed air chamber orspace and by its top Wall E, through which heat is communicated to the inclosed air-space and thence through the oven-floor to the ovenchamber.

G is a flue leading from furnace F and run ning toward the front side of masonry A,

upper side and near the front. Each flueextension J has a damper J 2 for opening and closing it, one damper being shown.

The furnace F and flue G and its flue-extensions J are all closed to the oven-chamber except when the dampers J 2 J 2 are open,

and, furthermore, they are severally closed to the inclosed air-chamber and space E above the furnace F and under the oven-floor.

K is a hood located at the front and on the outside of the oven masonry A, directly over the oven-floor O. The lower end K of the hood K is open and the upper end K is closed, and the inolosed space K of the hood has a flue-passage K which leads from it and opens at K into the chimney or escape flue (not shown) of the oven-chamber.

L is a flue leading from top of oven-chamber near its front to the chimney and located just back. of the hood-flue K.

M is a slide-damper for opening and closing chimney-flue L of oven-cha1nber, and also the hood-flue K.

The inclosed air chamber or space E below oven-floor and over furnace F, but closed to both oven chamber and furnace, in combination with the flue passage or passages leading from the furnace directly into the oven-chamber and from the oven-chamber to the chimney, severally having dampers to open and close them, enable the heat of the oven to be most evenly, thoroughly, and effectively diifused about the oven-ohamber and to be maintained and regulated in the most practical and desirable manner for the requisites of the baking desired.

Having thus described my invention, what I claim,and desire to secure by Letters Patent, 1s

The combination, with a bakers oven, of

an ovenehamber B, closed on all sides and 5 having a door 0 to enter it and a floor D, an air space or chamber E, located directly under and embracing oven-floor D, which makes a roof or top thereto and closed on all sides and at all points to the oven-chamber, a furnace F,nnder the floor of air-chamber E, and closed at all points to said chamber, a furnace-flue H J, leading from furnace and openin g to upper portion of oven-chamber, a damper J to open and close flue H J, an oven and escape-flue L, leading from upper portion of oven-chamber, and a damper M, to

open and close flue L, substantially as de- IO scribed, for the purposes specified.

In testimony whereof I have hereunto set my hand in the presence of two subscribing Witnesses.

GEO. E. BAILEY.
